High Pressure Plant Washing Goldfields & Mid-West

High-Pressure Plant Washing for Mining and Industrial Sites

Built-up material around mills, conveyors and processing equipment restricts access and causes costly delays during inspections and shutdowns. Left unmanaged, this build-up – usually spilt product, process residue, grease and hardened material – becomes a safety and contamination risk. High-pressure plant washing clears it using pressurised water and mine-grade vacuum trucks.

In-Region Presence. Experienced People. Specialised Equipment.

GCW provides high-pressure plant washing across the Goldfields and Mid West for mine sites, processing plants and industrial facilities. We support scheduled maintenance wash-downs, shutdown cleaning and mill spill clean-ups. Our various-sized trucks use attachments specially designed for mining and industrial applications, and our in-region crews are certified to work at heights and in confined spaces.

Other high-pressure cleaning companies dispatch from Perth. Our fleet, workforce and infrastructure are already here.

How High-Pressure Plant Washing Works

High-pressure plant washing uses controlled water pressure to strip grease, product build-up and hardened material off plant and equipment without dismantling or damaging it. High-pressure pumps direct water at the affected surface before industrial vacuum hoses recover loosened material.

Our purpose-designed vacuum truck attachments capture runoff and displaced material as work proceeds. This contains the waste for tracked disposal and keeps the area safe to work in. Your team has clearer access to the equipment, whether for shutdown maintenance, plant upgrades or regular cleaning.

High-Pressure Plant Washing FAQs

What is high-pressure plant washing?

High-pressure plant washing uses pressurised water to loosen and remove built-up material from mills, conveyors, processing equipment and surrounding work areas. The loosened material and wash water are then recovered using an industrial vacuum truck.
